COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 773,80 9, dated November 1, 1904.

Application filed April 9, 1903.

T all whmn it Duty concern.-

Be it known that I, GEORGE S. RAMSAY, a citizen of the United States,residing at St. Marys, in the county of Elk and State of Pennsylvania, have invented a new and useful Coke- Oven, of which the following is a specification.

The invention relates to improvements in coke-ovens.

The object of the present invention is to improve the construction of coke-ovens, more especially that shown and described in an application for Letters Patent, Serial No. 109,754, filed by me in the United States Patent Oflice on or about the 31st day of May, 1902, wherein the gases and products of combustion are conveyed from the interior of the oven to tlues beneath the floor to maintain the latter in a heated condition and to cause the coking process to begin at the bottom of the oven as well as at the top, and thereby secure a complete coking of the contents of the oven and prevent the formation of the black spongy inferior coke and the black butts found in the ordinary beehive coke-oven where the coking process does not extend to the floor. In the said application the gases and other products of combustion conducted beneath the floor of the oven are excluded from the interior of the oven by a gas-excluding packing composed of fibrous and granular material, such as asbestos and sand. An absolutely gastight packing is thus provided for preventing the products of combustion from reentering the oven at the bottom thereof and consuming the charge.

The present invention is particularly designed to provide a floor structure or a floorsupporting structure of great strength and durability, adapted to aiford a firm support for the gas-excluding packing to prevent any liability of the latter accidentally breaking or collapsing under the weight of a large charge,.

and thereby permitting the gases and other products of combustion to reenter the oven and consume the charge.

Furthermore, the invention has for its object to connect each of the upstanding flues with the main flue of the bottom of the oven by means of an independent connecting bottom flue to enable the floor of the oven to be Serial No. 151,847. (No model.)

uniformly heated in a positive and effective manner and also to permit any one of the upstanding flues to be cut out; if desired.

l/Vith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to'without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is avertical longitudinal sectional view of a coke-oven constructed in accordance with this invention. Fig. 2 is a horizontal sectional view taken through a pair of adjacent ovens in different horizontal planes, one of these planes being above the floor and the other being below the floor to show the fines or passages for heating the same. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2. Fig. 4 is a similar view of one side of the oven on the line L 1 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a coke-oven, which is preferably circular, as illustrated in Fig. 2, and

which is provided with a dome-shaped topsimilar to that of the ordinary beehive type of oven. WVhile it is possible to use the ovens singly, it is preferable to arrange them side by side in close proximity and to wall up the fronts of the ovens with masonry at 2, there being also a wall of masonry at each end of the series of ovens. The intervening spaces between the masonry and the ovens and also the spaces between the adjacent ovens are filled with loam 4: in order to retain the heat within the oven and to increase the strength of the structure. At the center of the dome of each oven there is provided a chargingopening 6, through which coal is introduced into the oven, and a doorway 7 is formed through the front Wall of masonry for convenience 1n drawing the coke from the oven,

The upper end of each of the upstanding flues is open at a point slightly above the openings 26 of the oven and is normally covered by means of tiling 27 or other suitable means. The covering of brick or tiling which removably rests upon the top of the upstanding flue is held in place by the loam packed thereon and is adapted to be removed to afford access to the interior of the upstanding flue.

By the construction before described the floor of the oven is maintained in a highlyheated condition, whereby the coking of the coal commences at the bottom as well as at the top and a highly-intensified temperature is maintained throughout the entire interior of the oven, so that the coking is materially accelerated. The particular construction of the bottom of the oven enables the latter to be uniformly heated at the floor and at the same time affords a firm support for the floor and its gas-excluding packing and provides supporting flue walls which are connected with the walls of the oven to assist in sustaining them in proper position. ing packing is thus prevented from accidentally collapsing when the floor of the oven is subjected to the weight of a large charge of coal and there is no liability of the gases reentering the oven at the floor and consuming the charge. By providing a separate and independent conne'cting-flue for each of the upstanding flues the gases and other products of combustion entering the upstanding flues are compelled to take a prescribed course, and the direct draft through the main longitudinal flues enables the gases and other products of combustion to be drawn through the bottom connecting-flues, and the doors or dampers at the front ends of the main longitudinal flues control the draft in order that the gases will remain in the bottom flues a suflicient length of time to secure the desired combustion anda proper heating of the floor of the oven.

The chimney or stack is provided with a damper 28 to afford additional means for controlling the draft and the passage of the gases and other products of combustion through the said flues.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is- I 1. A coke-oven having a stack, and provided with a main bottom flue communicating at one end with the stack, front and rear upstanding flues communicating at their upper ends with the interior of the oven, and the independent front and rear bottom flues connecting the upstanding flues with the main flue, the flues on each side of the main bottom flue being independent of the flues on the opposite side and also independent of each other, substantially as described.

2. A coke-oven having a stack, and provided with a main bottom flue communicating The gas-eXclud-.

at one end with the stack, front and rear up- 7 standing flues commuricating at their upper ends with the interior of the oven, and the independent front and rear bottom flues connecting the upstanding flues with the main flue, the rear bottom flues being shorter than the front bottom flues, substantially as described.

3. A coke-oven provided with a stack, and having a main bottom flue communicating therewith, front and rear upstanding flues communicating at their upper ends with the interior of the oven, and front and rear bottom flues connecting the upstanding flues with the main bottom flue, the walls forming the bottom flues being continuations of the outer walls of the oven and forming continuous supports for the floor of the oven, substantially as described.

4:. A coke-oven having a stack, and provided with a central main bottom flue communicating at one end with the stack, front and rear upstanding flues communicating at their upper ends with the interior of the oven, and the independent front and rear bottom flues connecting the upstanding flues with the main bottom flue, the rear bottom flues being shorter than the front bottom flues, and the walls separating and forming the front and rear bottom flues being continuations of the outer walls of the oven to provide continuous supports for the floor of the same, substantially as described.

5. A coke-oven provided with a stack, and having a centrally-arranged main bottom flue communicating at one end with the stack, front and rear upstanding flues communicating at their upper ends with the interior of the oven, and the independent front and rear bottom flues connecting the upstanding flues with the main bottom flue, and each consisting of an outer radial portion, and an approximately U-shaped portion or loop, substantially as described.

6. A coke-oven provided with a stack, and having a central main bottom flue communicating with the stack, front and rear upstanding flues, and the independent front and rear bottom flues of unequal length, the rear bottom flues being shorter than the front bottom flues, and each bottom flue consisting of a short outer radial portion, an intermediate U-shaped portion or loop, and a short inner transverse portion, the interposed walls between the bottom flues being continuous and connected with the walls of the oven to provide continuous supports for the floor of the same, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

GEORGE S. RAMSAY.
